Effect of asymmetric power distribution in bipolar reactive sputtering on the optoelectronic and microstructure properties of titanium dioxide for solar water splitting

Titanium dioxide is one of the most commonly used materials for solar water splitting, because of its excellent corrosion resistance. However, its optoelectronic properties are not sufficient to achieve high solar to hydrogen conversion. It is known that the choice of deposition method has a great influence on the optoelectronic and structural properties of titanium dioxide.
